During 2018 negotiations China's vice premier Liu He asked finance business leaders "We need your help." This included  Black Rock, Goldman Sachs, JP Morgan, and others. In exchange China which has protected its financial markets from American finance companies now offered to give some opportunities, though as other companies in other industries have found out this could be limited by other priorities. 

The Trump and now the Biden administration are pursuing the decoupling of the Chinese and American economies after learning through two decades that it is damaging to the U.S. economic position in the world. The new law passed by unanimous vote in Congress to be signed into law by president Trump requires Chinese companies to have financial audits inspected by U.S. regulatory agency for them to remain listed on U.S. exchanges. However as the WSJ points out in a separate article this does not restrict Chinese companies access to global capital in unfair competition with the U.S. because the law goes into effect over 3 years giving Chinese companies. American investors can also invest in the Chinese companies on the Hong Kong stock exchange unless their entire thinking process changes seeing what is best for America as best for them.
